摘要：A series of studies have been carried out for the removal of Rhodamine-B dye from waste water using Pigeon Dropping as adsorbent. The effects of contact time, concentration of the adsorbate, adsorbent dosage, pH and temperature have been studied. The adsorption process was well described by Langmuir and Freundlich adsorption isotherms. The adsorption followed pseudo-second-order rate equation and the intra particle diffusion equation. The thermodynamic studies sho wed that the process is exothermic and spontaneous. This study investigates the potential use of Pigeon Dropping for the removal of d ye.
